LEMUEL L. LONG, OF TOLEDO, OHIO.

MOLD-JACKET.

To all whom it may concern:

Be it known that I, LEMUEL L. LONG, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Mold-Jacket; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to foundry apparatus, and particularly to mold jackets.

The object of my invention is to provide a simple and eflicient jacket of this character, which is light, strong and durable in its construction, inexpensive of manufacture, and adjustable to obviate the objections incident to jackets of this class commonly used.

The invention is fully described in the following specification, and while, in its broader aspect it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure 1 is a perspective view of my improved jacket incasing a mold with a portion of the latter broken away. Figs. 2 and 3 are enlarged side and top views, respectively, of a separable corner portion of the jacket, and Fig. 4 is an enlarged view of an end portion of one of the jacket sections.

Referring to the drawings, 1 designates a mold, and 2, 2 like halves or sections of a jacket for the same. Each of the jacket halves or sections comprises two connected sides or a side and end portion of a jacket, which are relatively angled as the shape of the jacket may require, they being shown in the present instance as at right angles one to the other to cooperate with the other half or section to form a rectangular jacket. Each section 2 is preferably formed of a single piece of sheet metal which is bent as the shape of the section may require and is reinforced by an angle-bar 3, which is bent to conform to the shape of the section and is secured to the outer side thereof for substantially its entire length by rivets or in any other suitable manner. While the reinforcingv member is shown as comprising an angle-bar, it is apparent that any other Specification of Letters Patent.

suitable form of reinforcing means may be used if desired.

When the jacket sections are placed around a mold the adjacent ends of the two sections are secured together in an adjustable manner by suitable clamping means, each of which is shown as comprising the inner clamping block a, the outer clampin bars 5, 5, and the securing screws 6. Each block 4 is of a shape suitable to fit the corner of the jacket with which it is associated and to fill the space which is left at the corner of a mold by the corner construct-ion usually provided in two of the corners of a flask. A bar 5 is clamped against an associated end of a jacket section in opposition to the section-coacting sides of the block 4, while the screws 6 project through registering apertures in the bars and ends of the jecket sections and thread into the block 4, thus serving to tightly clamp the sect-ion ends between the bars 5 and block 4 when the screws 6 are tightened.

It is found in practice that flasks, which are commonly made of wood, are not of exact uniform sizes, and also that the drying to which they are subjected in use causes a slight contraction thereof, thus making the molds formed by different flasks which are supposedly of the same-size or by the same flask vary slightly in size. In order that the jacket may be adjusted to closely fit a mold irrespective of the exact size thereof the ends of the sections 2 are provided with longitudinally-extending elongated notches or slots 7 through which the screws 6 work. This manner of clamping the section ends together enables such ends to be rigidly secured together in substantial abutment, as indicated in Fig. 1, or to be retracted from endwise abutting positions to a limited extent, as shown in Fig.

3, as it may be desired to enlarge the jacket to fit the mold.

It is apparent that I have provided a strong and inexpensive mold jacket the sections of which are capable of being easily and quickly clamped closely about a mold to prevent even the slightest expansion of the mold and to be adjusted as the conditions of use may require.

I wish it understood that my invention is not limited to any specific construction or arrangement of the parts except in so far as such limitations are specified in the claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,

1. A mold jacket comprising at least two angular sections having longitudinally slotted ends, inner clamping blocks disposed Within the corners formed by the meeting ends of the sections, outer clamping bars coacting with said blocks to clamp the section ends thereto, and means passing through said slots for securing the blocks and bars in clamped relation.

2. A mold acket comprising at least two angular sections, said sections being formed of single piece sheet metal strips and having angle iron reinforcing strips secured to their outer sides lengthwise thereof, the ends of said section strips being longitudinally slotted, clamping blocks fitting into the corners formed by the meeting ends of the sections, bars acting to clamp the section ends in opposition to said blocks, and screws project ing through said bars and section slots and threading into said blocks, substantially as described.

3. The combination with a mold having diagonal corners thereof chamfered, of a mold jacket therefor comprising two i.- shaped sections which cooperate to completely encompass the mold and have their meeting ends disposed at the chamfered corners of the mold and each longitudinally slotted, clamping blocks fitting into the spaces formed by the chamfered corners of the mold and the meeting ends of said sections, and means projecting through the slots provided in the section ends and engaging said blocks to rigidly clamp the blocks and mold sections together in ad justed relation.

4. The combination with a mold having diagonally opposing corners thereof chamfered, of a mold jacket therefor comprising two angular sections the ends of which meet at the chamfered corners of the mold and are longitudinally slotted, blocks fitting into and filling the spaces formed by the chain fered corners of the mold and the meeting ends of the acket sections, a clamping bar at the end of each section in opposition to a side of the'associated block, and screws projecting through said bars and section slots and threading into said blocks to rigidly clamp the jacket sections, blocks and bars in adjusted mold embracing position.

In testimony whereof, I have hereunto signed my name to this specification in the presence of two subscribing witnesses.
